How to access phone from laptop?

My bro has Samsung A30 which he is using since July 2019. Few days back, he dropped his phone on the floor due to which his screen got blackout. His phone can accept calls and this means only his display is gone.

He is without internet for last few days. He has a laptop but he cannot use internet in that without his phone.

His plan is to access his phone though laptop and enable wifi hotspot. Since his phone has pattern lock, he cannot access it.

He doesn't have any Hdmi cable.
